This NU Aqua Polishing carbon filter is a direct replacement for the NU Aqua Platinum Series Reverse osmosis system. This filter will work with standard systems and requires 1/4” NPTF fitting for attachment. Using only the most refined carbon these filters maximize the removal chlorine, odor and taste. Giving your water it's final polish before it's pure and ready to drink.
I am not replace parts yet, I use this system very litle, (couple cup coffee a ). My , I will do by annual or more.
Been using this filter, it's good product.
The only complaint I have is that the replacement filter didn't match the original filter quick disconnect. I had to adapt it to make it fit, so it took a trip to town to get something that would work.
